I know I'm probably late to the game on this one (no pun intended) , but my favorite book of the year was definitely Ready Player One. I listened to a lot of it in the car (Wil Wheaton narrated) and it was fabulous.
I also loved the third book in The Great Library series:
And I finished The Others (which is one of the best series I have read in a loooong time):
I completed my (non workelated) reading challenge of 52 books, but just barely. I set the same goal this year and am hoping to come in above it.
